Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Provide me a one-paragraph summary of this article that an eight-year-old would understand.

Black holes have incredibly powerful gravitational pulls. They usually gobble up everything around them. However, for the first time ever, scientists have found a black hole that is creating millions of stars as it zips through space.

Pieter Van Dokkum, a professor of Astronomy and Physics at Yale University, made the exciting discovery accidentally. He was looking for star clusters in an image captured by NASA's Hubble Telescope when he spotted a light trail.

"I was just scanning through the Hubble image, and then I noticed that we have a little streak. I immediately thought, 'oh, a cosmic ray hitting the camera detector and causing a linear imaging artifact.' When we eliminated cosmic rays, we realized it was still there. It didn't look like anything we've seen before," Dokkum explains.

Curious to know where the light trail was coming from, Dokkum and his team decided to investigate further. They used the powerful telescopes at Hawaii's Mauna Kea Observatory. To their astonishment, they discovered that the streak was from a 200,000-light-year-long chain of newborn stars. This is twice the diameter of our Milky Way galaxy.

The scientists say the stars are caused by a supermassive black hole racing through the gas clouds at an unbelievable speed. If it were in our solar system, the black hole, which weighs as much as 20 million Suns, could travel from Earth to the Moon in just 14 minutes. This is too fast for it to catch anything in its path. Instead, it is creating a string of new stars.

"We think we're seeing a wake behind the black hole where the gas cools and is able to form stars. So, we're looking at star formation trailing the black hole," Dokkum said.
Response: Scientists recently discovered a black hole that creates stars as it moves through space. The discovery was made accidentally when a professor was scanning images from NASA's Hubble Telescope. The light trail he saw was actually from a chain of stars that's twice the diameter of the Milky Way galaxy. Scientists think the stars are caused by the giant black hole traveling through gas clouds at an incredible speed.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Describe how volcanoes are formed in one paragraph.
user
Volcanoes form when magma from within Earth's mantle works its way to the surface. This happens mainly at tectonic plate boundaries, where plates are either colliding or moving apart. As the magma rises, it creates pressure, and when it reaches the surface, it erupts, releasing lava, ash, and gases. Over time, these eruptions build up to form a volcanic mountain.
